ADATA Premier Pro SP920 256GB Solid State Drive Review

ATTO

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Unconditioned

Conditioned

From start to finish we can see that there is virtually no deviation in the baseline performance that this drive has to offer. Granted the write speeds are a bit off the mark when compared to a number of other drives on the market, but it’s the read speed that really matters here.

Drive Comparison

For the purpose of drive comparison I use the performance figures from both unconditioned and conditioned tests with 0% data fill.

Following the introduction to the SP920 I was expecting this drive to be one of the top contenders for out-and-out SATA performance and ADATA’s drive was eager to please. With a read speed that tops 560MB/s this is by a short stretch the fastest drive that I have tested on a SATA III interface to date – hopefully the real world speeds can follow suit.
